Abstract
In an electro‐mechanical valve actuated engine, the valves are driven by solenoid‐type actuators and cam‐shaft is eliminated. Individual control of each valve provides flexibility in valve timings over all engine conditions and fully exploits the benefits of variable valve timing. This paper pertains to the closed‐loop control of an electro‐mechanical valve actuator. The primary emphasis is on the soft‐seating problem, in which the valve and the moving actuator parts need to be brought to a soft‐stop at the end of their travels. The actuator control features which provide reliable valve motion are discussed in detail. Several illustrative experimental results are also presented. Copyright © 2004 John Wiley & Sons, Ltd.
